Coordinate Plane and Classifying Shapes

Aligned to 5.G.A.1 — Common Core State Standards for Mathematics.

What this lesson teaches

The coordinate plane uses two number lines that cross to locate points. A point is named by an ordered pair (x, y): the first number tells how far right, the second how far up. You can also classify shapes in a hierarchy, since a square is a special rectangle.

Worked example

Plot the point (3, 2). Start at zero, move 3 to the right, then 2 up. That spot is the point (3, 2).

Practice questions

  1. Where do you move to plot (4, 1)?
  2. In the pair (5, 0), what does the 0 tell you?
  3. Why is every square also a rectangle?

El Plano Cartesiano y Clasificación de Figuras

El plano cartesiano usa dos rectas numéricas que se cruzan para ubicar puntos. Un punto se nombra con un par ordenado (x, y): el primer número indica cuánto te mueves hacia la derecha y el segundo cuánto te mueves hacia arriba. También puedes clasificar figuras en una jerarquía, ya que un cuadrado es un rectángulo especial.

Ejemplo: Grafica el punto (3, 2). Empieza en cero, muévete 3 hacia la derecha y luego 2 hacia arriba. Ese lugar es el punto (3, 2).
